Hi,
to add a system folder such as /usr/local, open the "Add Files to..." dialog,
press Command+Shift+G, and enter the path directly.
Great. That got me halfway.
After adding the frameworks QtGui, QtWidgets and QtCore and adjusting the
include statements to
#include <QtGui/QtGui>
#include <QtWidgets/QtWidgets>
the compilation ends with the following error:
/usr/local/qt5.1.0/lib/QtCore.framework/Headers/qlist.h:52:10:
'initializer_list' file not found
According to (http://comments.gmane.org/gmane.comp.lib.qt.user/8357) and (the
subsequent links) this is due to Qt requiring -stdlib=libc+ (not libc++ ?) and
c++11 - which is in conflict with libstdc++ that is required by Gecode. Hmm.. I
can't figure out to get passed this - tried varies ways in Xcode, but no luck
so far. Should I perhaps download and install Qt directly from the source
rather than using the version coming with Gecode?
I will probably build new packages soon based on libc++ and linked to the
newest version of Qt, but until then you basically have two alternatives:
compile Gecode from sources with libc++, or compile Qt from sources with
libstdc++.
Great. I will await the new builds. And until then I'll do without Qt.
On the command line, I think Xcode may have changed the default paths for
frameworks, you could try adding -F/Library/Frameworks to your compiler options.
That almost did the trick. Again I had to add options for selecting libstdc++
etc, but still I get an error. After trying the (what I think) options that
Xcode uses I get:
$ g++ -std=gnu++11 -stdlib=libstdc++ -O3 -F/Library/Frameworks -c money.cpp
money.cpp:1:1: error: expected unqualified-id
<U+001C>/* -*- mode: C++; c-basic-offset: 2; indent-tabs-mode: nil -*- */
^
Have a look at the money.cpp file, looks like there's a funny character on the
first line.
:-§ That was a creepy one! And I had to pick just that file... Removing
the character did the trick. Maybe you should fix that in the next build
as well.
And in MGP section 2.3.2 there's some minor issues:
1) Correct the command line example - the last line should at least end
with send-more-money.o
2) Update the Xcode description regarding adding frameworks
Thanks again for your help!
